You have to be careful here because xPCS supports much more than these interfaces and speeds.
I would implement this thinking about the future integrations and leaving margin for more speeds.
As for this being a converter I'm not sure about the implementation logic because sometimes you can have a setup like:
MAC <-> xPCS <-> SERDES <-> SFP
SERDES and SFP may not require configuration nor even have MDIO access so in my view the "PHY" would then be the xPCS, no ?
